10 Gigabit Ethernet switching
The Summit X670 model offers 48-port 10 Gigabit Ethernet non-blocking switching with 10GBASE-T interfaces. Summit X670 is capable of layer 2 and layer 3 forwarding at up to 714 million packets per second forwarding rate in a small 1RU form factor, enabling next-generation high-performance server deployment in data centers. And the X670 supports SummitStack-V high-speed, longer distance stacking over the 10GbE ports.

SummitStack-V - flexible stacking over 10 Gigabit Ethernet
SummitStack-V capability utilizes 10 GbE ports as stacking ports, enabling the use of standard cabling and optics technologies used for 10GbE BASE-T RJ45 and BASE-X SFP+ available on the X670V-48t. SummitStack-V provides long-distance stacking connectivity of up to 40 km while reducing the cable complexity of implementing a stacking solution. SummitStack-V enabled 10 GbE ports must be physically direct-connected.

40 Gigabit Ethernet uplinks and high-speed 160 Gbps stacking
The Summit X670V-48t switch can support an additional four QSFP+ ports of 40 GbE. With this option, you can maximize the number of interfaces for servers up to 48 ports while using the dedicated four-port 40 GbE module for uplink connectivity. Summit X670V-48t together with VIM4-40G4X provides high speed stacking options running at 160 Gbps or 320 Gpbs through the SummitStack technology. SummitStack-V160 can be enabled on two 40 Gigabit Ethernet QSFP+ ports on the VIM4-40G4X, using half of the module's four ports as stacking interfaces. SummitStack-V320 can be enabled on all four 40 Gigabit Ethernet QSFP+ ports on the VIM4-40G4X, using all of the module's four ports as stacking interfaces.

Green design
The Summit X670 series is designed to be environmentally green. System power consumption is very low at both high-load and idle situations through the power-efficient hardware design. The power supplies are also highly efficient, which minimizes the loss of power and unnecessary heat generated by the power supply. Summit X670 series switches can be used in AC or DC powered environments.

Supports virtualized data centers
With the feature pack, Summit X670 switches can also support Direct Attach (VEPA), which eliminates the virtual switch layer, simplifying the network and improving performance. To further enhance data center operations, Summit X670 switches support XNV (ExtremeXOS Network Virtualization), which is natively supported in the ExtremeXOS operating system and is a licensable feature pack for Ridgeline, a network and service management application, sold separately. XNV provides insight, control and automation for virtualized data centers. Summit X670 switches also support Priority-based Flow Control (PFC, or IEEE 802.1Qbb), which allows network traffic to be controlled independently based on Class of Service. PFC allows network traffic that requires lossless throughput to be prioritized, while other traffic types that do not require or perform better without PFC can continue as normal.

DCB support with enterprise core class scalability
The Summit X670 series supports data center bridging features such as Priority Flow Control (PFC), Enhanced Transmission Selection (ETS) and Data Center Bridging eXchange (DCBX) for data center convergence. At the same time, the Summit X670 series offers more cost-effective 10 Gigabit Ethernet switches, for both small-sized core backbone and traditional three-tier network architectures. Summit X670 series can support 10 Gigabit Ethernet campus aggregations with its core class routing and switching scalability. The Summit X670 series can support up to 16000 IPv6 longest prefix matching routing tables, 6000 IP ARP entries and 3000 IP multicast group entries.

10 Gigabit Ethernet copper
The Summit X670-48t switch supports 48 10GBase-T interfaces. 10GBASE-T supports simpler cabling infrastructure, industry- standard and commonly used unshielded twisted pair cable, and can support up to 100 meters with Category 6a or 55 meters with Category 6 or 5e cable.

10 Gigabit Ethernet SFP+
The Summit X670-48t switch supports 4 ports SFP+ optics on shared combination ports, which can support passive copper cable for up to 10 meters. The switches also support fiber-optical cable installation with SFP+ transceivers such as 10GBASE-SR, LR, LRM, and ER. Summit X670 SFP+ ports support dual interface speeds of Gigabit Ethernet and 10 GbE. SFP+ ports can accept both gigabit SFP and 10 gigabit SFP, and depending upon the pluggable optics you choose, SFP+ can work in both modes.

40 Gigabit Ethernet QSFP+
The Summit X670V model provides a VIM4 slot for the optional VIM4- 40G4X module. The VIM4-40G4X module supports four QSFP+ optics, and supports up to four ports of 40 GbE. 40 GbE QSFP+ ports can accept QSFP+ passive and active cables, as well as QSFP+ transceivers. Each 40 GbE port can be configured as a 40 GbE port or as four 10 GbE ports. The 10 GbE port mode can be supported by a 40GBASE-SR4 QSFP+ transceiver and fan-out optical cables, and is compatible with the 10GBASE-SR optical interface for distances up to 100 meters.

Low power consumption with optimized cooling options
The Summit X670-48t switch consumes low power and provides optimized cooling options. Most servers installed in a standard 19-inch rack system flow air from front to back to maximize cooling performance. Compared to side-to-side air flow, front-to-back air flow provides more effective cooling throughout the rack system in the data center. The Summit X670 series has 2+1 hot swappable fan tray offering effective front-to-back air flow, or back-to-front air flow. Back-to-front air flow allows placement of 10 Gigabit Ethernet SFP+ ports in the back side of the rack and reduces distance between switches and servers for 10GBASE-CR SFP+ passive copper cable installations.

Link aggregation (802.3ad)
Link aggregation allows trunking of up to eight links on a single logical connection, for up to 80 Gbps of redundant bandwidth per logical connection.

Hardware redundancy
Summit X670 series switches support a dual redundant AC/DC power supply to provide high availability. The power supply can be hot-swapped and replaced should it fail. Summit X670 also supports N+1 redundant hot-swappable fan trays.

Port mirroring
To allow threat detection and prevention, Summit X670 supports many-tone and one-to-many port mirroring. This allows the mirroring of traffic to an external network appliance such as an intrusion detection device for trend analysis or for utilization by a network administrator for diagnostic purposes. Port mirroring can also be enabled across switches in a stack.

Denial of service protection
Summit X670 series effectively handles Denial of Service (DoS) attacks. If the switch detects an unusually large number of packets in the CPU input queue, it assembles ACLs that automatically stop these packets from reaching the CPU. After a period of time these ACLs are removed, and reinstalled if the attack continues. ASIC-based LPM routing eliminates the need for control plane software to learn flows, allowing more network resilience against DoS attacks.
